Abstract
Tungsten carbides are very attractive because of their superior properties, e.g., high thermal and electrical conductivities, high melting point, high hardness, and relatively high chemical stability. Tungsten carbides with a binder metal, for example Ni or Co, are mainly used to fabricate nozzles, molds and cutting tools in the composite..... More

Abstract
This study conducted an analysis of the carbothermal reduction of oxidized WC/Co hardmetal scrap with solid carbon under an argon and hydrogen gas atmosphere. The WC/Co hardmetal scrap oxide consisted of WO₃ and CoWO₄. WO₃ was reduced before CoWO₄ by the solid carbon regardless of gas atmosphere. The simple oxide..... More
